They sacked him, LOL, Consider buying his book
From 2009 to 2012, the NRC Chairman was Dr. Gregory B. Jaczko. Appointed by President Barack Obama, Jaczko had previously served as a Commissioner since 2005. During his tenure, he emphasized strengthening nuclear safety regulations, particularly in the aftermath of the 2011 Fukushima Daiichi nuclear disaster in Japan. Notably, he was the sole dissenting vote against the construction of new reactors at the Vogtle plant in Georgia, citing safety concerns stemming from the Fukushima incident.

Jaczko’s approach often put him at odds with other commissioners and industry stakeholders. In 2011, an NRC inspector general report highlighted concerns about his management style, including allegations of creating an intimidating work environment. These internal conflicts, combined with his regulatory stance, led to mounting pressure. On May 21, 2012, Jaczko announced his resignation, stating he would step down upon the confirmation of his successor.

Following his departure from the NRC, Jaczko became an outspoken critic of nuclear energy. In his 2019 memoir, Confessions of a Rogue Nuclear Regulator, he detailed his experiences at the NRC and expressed concerns about the safety and viability of nuclear power.

Jaczko’s tenure and subsequent advocacy have been subjects of debate, reflecting broader discussions about nuclear energy’s role in the U.S. energy landscape.
